Error message: the bookmarks and history system will no be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I tried following the directions in "learn more" but to no avail. Please help this senior citizen get his bookmarks back! Thank you.

I've used Firefox for 20 years through the various iterations of Windows, and have been using it trouble free on Windows 11 since November 2024. Two days ago, however, When I tried to open the Guardian site (www.theguardian.com) it would open very slowly and not load and of the pictures. This gradually got worse, the site taking for ever to open at all, and always with the little dot in the tab at the top left going from side to side showing it was still loading. I have tried everything I can think of. Opened in troubleshoot mode, changed DNS settings, uninstalled and reinstalled Firefox twice (one time to see if it would work normally if I didn't actually sign in to my account). All to no avail. In fact now things are worse, in that the GOV.Uk website is now giving me similar problems - and a few other sites have become slightly slow and reluctant to open as well. My internet connection seems fine, and all these sites open without any trouble on Microsoft Edge. I am NOT very good at tech, and I am now tearing my heair out as to what I can try next.

Any help wopuld be gratefully received!

When I attempt to search on Mozilla Firefox I get this message from Norton, my antivirus software provider: "We prevented your connection to rini.drorinat.com because it is a dangerous webpage:URL:Phishing" This has only happened in the last few days. I am offered no sites - just this message from Norton. How can I solve this, as Norton does not appear to offer a solution, though I have messaged them on their site.

The site chatgpt.com demands challenges.cloudflare.com to be allowed. I visited this site and allowed cookies. Then it worked. However, the chatgpt.com site froze and when I reloaded it, I had to start all over again. This time, the request for challenges.cloudflare.com remains, even though a URL attachment is reloaded every few seconds. The same thing happens on the openai.com site and several other. I'm using windows 7.1 and ESET Smart Security Premium.

I know the sites are secure (unless something is happening that I don't know about). I just want to get onto them, especially the Christmas site. Is it to do with Bitdefender?? I hope someone can help as the letter I want to write is getting time sensitive.

Near the top of the Firefox page is displayed:

"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can caused this problem".

How do I resolve this problem?

Hello, I'm an avid user and supporter of Mozilla Firefox. But I installed AVAST as an additional protection tool...and I have just subscribed today to Avast Antitrack to avoid being tracked and hacked. But, to enable AntiTrack, I'm now prompted to add it to Firefox !? Before any action, I'd like to know that this will be efficient and safe : can you confirm that this is compatible with Firefox's proper operation? Thank you, P.Huens.

Hello, Iam using Bitdefender Secure Pass as passwordmanager, but since one or two weeks I have problems with the functionality on the laptop. I just can't open it. It is popping up and closing down immediately. Autofill in is not working as well. This is only when I use firefox, in chrome it is working. And on my mobile it is also working in firefox. I deinstalled and reinstalled the add on in firefox already. Afterwards it worked for a short time, but now it is the same again. Does somebody have experience with Bitdefender and an idea what I could do? Thank you in advance. Sabine

Is Webroot a part of Mozilla/Firefox? When Firefox recently updated it began to ask for a Webroot access key and it takes me to this page. I have never signed up for Webroot before.

Every time I access the web I get a report from Norton saying "Threat secured". It attaches every single website that I open. See attachment for some exmaples (only variabole part of message shown apart from first one).This is occuring 50+ times a day but does not occur using Edge, so it appears to be related to Firefox. PLEASE help. Norton have not helped with this. Thank you- Colin O'Brien

I am trying to connect with my utility provider online. When I try to log in, I give my name and password. It comes up with a CAPTCHA screen. I click on the items but I just keep getting another screen. After a dozen screens it says CAPTCHA will time out in 2 minutes.

Does anyone have any ideas what could be blocking it?

OK, this is getting to the point where I no longer want to use Firefox. I have had trouble in the past where if I went on Edge for some reason and logged in to my email, when I returned to Firefox I was logged out of all my Yahoo powered email accounts. When trying to log on I would receive the attached message and it would take hours, and sometimes days to be able to log on. Even when I was logged on to my main mail account, I would not be able to log on to the other two accounts. The last time this happened is when I realized it coincided with me logging into my email on Edge, so I have not logged into my email using Edge since then. Unfortunately that was just a coincidence, because it happened today and I hadn't been on Edge since I posted my previous question in February.

I am always logged into all three accounts, but since this happened two months ago, I only logged into my main account and one other on Firefox, but I have only accessed the main account since logging in to both of them. I only accessed the other two accounts on my phone, which was fine, but I sent my phone to get the fingerprint sensor repaired so I'm using my wife's old iphone now. Don't get me started on how this phone sucks, but I needed to access one of the other accounts today and I don't have either of them set up on the Yahoo app, and I didn't want to take the time to set up the one now when my phone should be back in my hands in a couple of days. I came in the house and fired up my computer again opened my email and switched to the account I needed and surprise! I was logged in. I did what I needed to do and tried to switch back to my main email when surprise again! I received that same dreaded message.

I have been trying to log in to my account on and off for about five hours now, and I'm about to toss my notebook across the room. That would leave me without a PC though, so I am forced to use Edge, but for how long? I have posted on Mozilla support many times in the past for different things, but I have never actually had anyone from Mozilla provide an answer to any of my issues. Is that because this is only a community forum? Does anyone that works for Mozilla or Firefox actually access this forum and see these questions? If it's only a community forum, where do I get post my issue to be able to receive answers from the people that make Firefox work? My last post in February had 17 views, seven others that have the same issue, (so I'm not the only one), and no replies other than my posts adding content because you can't edit your original post. Evidently the people that have an answer to my problems haven't seen it.

Maybe I selected the wrong topic? I don't remember what topic I selected two months ago, but I selected passwords and sign in today, so hopefully it's not the same topic and maybe I'll receive some input this time.

Thanks in advance.
